氣體出口孔
英文
gas outlet hole-
The bag has wave - type rope, and is densely covered with air holes ; the bottom of the bag has air outlet ; the hanging hole is clearly marked, hence it is convenient and highly practical
袋體自帶波浪型繩條，袋面密布透氣孔，袋底留有出氣口，掛孔特殊標記，方便實用。For membrane contactor process, the binary gas mixture diffusion through the pore channel should be considered as a transition diffusion of the absorbed momentum a through the stagnant momentum b. and the process would consist three steps : transition diffusion through the pore channel, stephen diffusion in the pore edge, and the pore interaction in the membrane surface
對于孔形狀為近似橢圓形的聚丙烯微孔膜，在研究擴散問題時，其等效孔徑可採用葉孔擴散問題中的孔形狀校正公式來計算。在膜接觸器中，氣體通過微孔膜的擴散機理為過渡擴散，其擴散過程包括通過孔道主體的過渡擴散、微孔膜出口處孔道邊緣的stephen擴散以及孔之間的相互作用。When in experiment, the air was heated by the film heater installed on the above and below surface of channel, adopting various air velocity of flow, test import ' s and export ' s temperature, wall temperature, fluid flux and the drop of pressure, and the other parameter. adopting nu and nu0 to analyze the baffle ' s situation of heat transfer and fluid flow, which baffle was holed various diameters
實驗時，通過矩形通道上下壁面敷設的電加熱膜加熱通道空氣，改變空氣流速，測試不同工況時的進出口溫度、壁面溫度、流體流量和壓力損失等參數，並採用無量綱努謝爾特準則數nu 、 nu _ 0等分析了設置不同開孔折流板的換熱與流動情況。Results showed that due to the sharp difference between diameters at the upper and lower parts of the canal, the high - speed air - flow at the lower - end opening can drain the fluid below the opening out while the lower - speed air - flow al the upper opening is not likely to make the saliva and see page in the oral cavity reenter the root cavity
結果發現：由於根管兩端管逕相差懸殊，根尖孔?生的高速氣流沖擊，吸引根尖液，可引流低於根尖孔的液體；另一方面，開髓孔低速氣流不易將口腔內唾液、滲出物重新帶入根尖腔。分享友人
